Is preheating required for grill mode in lg microwave?

Preheating is not typically required for grill mode in LG microwaves, as this function is designed to cook food using direct heat from the grill element. However, for optimal results, it's advisable to allow the microwave to run for a short period before placing the food inside to ensure even cooking. Always refer to the specific user manual for your model for the best practices and recommendations.
